对国内外一些生产厂家的氢气再生装置进行比较,找出国内氢气再生在设计、工艺、操作和设施方面存在的问题,氢气再生系统没有有效的稳压措施,造成氢气流量的波动;用冷冻水方法冷凝氢中含水弊端很多,特别是在炎热的夏天会造成氢气露点的波动;干燥塔使用多的自动阀,难免会出现故障,造成各种不同后果。建议采用钟罩式气柜、氢气再生系统增压和改进新鲜氢气补充方式等办法,解决氢气流量波动和安全问题;建议直接采用冷干机冷冻氢气进行脱水,采用四通阀替代自动阀,从而解决氢气露点和故障多发问题。
Some domestic and foreign manufacturers of hydrogen regeneration device to compare to find the domestic hydrogen regeneration in the design, technology, operation and facilities of the existing problems, hydrogen regeneration system does not have effective voltage regulation, resulting in hydrogen flow fluctuations; with frozen water Methods There are many disadvantages of condensation of hydrogen in water, especially in the hot summer will cause hydrogen dew point fluctuations; dry tower using more automatic valves, it will inevitably lead to failure, resulting in a variety of consequences. It is suggested that bell jar type gas cabinets, hydrogen regeneration system pressurization and improved fresh hydrogen replenishment methods be adopted to solve the problem of hydrogen flow fluctuation and safety. It is recommended to directly use the cold dryer to dehydrate hydrogen gas and replace the automatic valve with a four-way valve. Solve hydrogen dew point and fault multiple problems.
